The folio edition in my own library comprises the Observations, and Dissertations of Ducange, and the Commentaries of Claud Menard; together with the Establishments of St. Louis, and a curious treatise upon the ancient law of France, by Pierre de Fontaines. All these works afford a great insight into the spirit of that day; and many other particulars are to be found in the _Branche aux royaux Lignages_, and in the Sermon of Robert de Sainceriaux. Besides the authors I have here particularized, I have had occasion to cite casually a great number of others, whose names, with some account of the works of each, may be found in the _Manuel_ of Brunet. Vertot also has furnished us with much information concerning the Knights of St. John; and Dupuy, Raynouard, &c. have spoken largely of the Templars. I cannot close the enumeration of authors to whom I am under obligations for information or instruction without mentioning M. Guizot, one of the most clearsighted and unprejudiced of all modern historians. His views of causes I have often adopted, sometimes with very slight modifications, and sometimes with none; and, in all instances to which his writings extend, I have been indebted to him for light to conduct me through the dark sanctuary of past events, to the shrine of Truth, even where he has not unveiled the deity herself. I can only regret that his essays did not embrace more of the very comprehensive subject on which I was called to treat. Several motives have impelled me to give this long account of my authorities; one of which motives was, that often, in reading works on history, I have myself wished that the sources from which facts were derived had been laid open to my examination; but still, my principal view in the detail was, to show the ground on which I had fixed opinions directly opposed to those of several other authors. In many cases, the aspect under which I have seen the events of the Crusades has been entirely different from that under which Mills has regarded them, and I felt myself called upon not to attack any position of a clever writer and a learned man, without justifying myself as completely as possible. In regard to my own work I shall say nothing, but that I have spared neither labour nor research to make it as correct as if it had appeared under a much more imposing form. In space, I have been confined; and in time, I have been hurried: but I have endeavoured to remedy the one inconvenience, by cutting off all superfluous matter; and to guard against evil consequences from the other, by redoubling my own exertions. Whether I have succeeded or not the world must judge; and if it does judge with the same generous lenity which it has extended to my other productions, I shall have every reason to be both satisfied and grateful.
